    I prefer this option, hopefully it's the real one

    Simple logic: if this is the loss of two military satellites in a row, we will soon see resignations among the leadership of the Space Forces. If not, then...

    Is glonass sufficient for guiding satellite guided bombs against movin g targets in Ukraine? Can russians spot ukrainian moving trains in real time through satellites?

    Of course not

    Spy satellites are only above a given location once per orbit. In theory they can be put into a geosynchronous orbit, but those orbits tend to be further away from Earth and you won't get sufficient resolution. Maybe that's going to change with the latest tech and optics.

    You're also not going to spot much at night either, satellites depend on the reflection of sunlight from the Earth. Or when its cloudy

    Western GPS is useless for tracking and hitting moving targets, how could GLONASS manage that?

    A moving target by definition changes its ground or air coordinates... as it moves.

    Using map coordinates to hit such a target would require you know the coordinates of the target at the time you hit it with the weapon.

    There are two ways to do that with a train target... blow up the tracks en route so the train has to stop there and then hit it with satellite guided weapons... but you would need a few because you can't be sure where they are going to stop and how long they will stay before reversing out of this obvious trap.

    The othe option is to hit the station it is taking the supplies to... just as it arrives....

    Obviously with a target like a train I would use the fact that train tracks are visible and don't have sharp turns... 100km down the track from where your target is expected launch a Kh-59M (HATO codename AS-18 Kazoo) which has been in service for a very very long time now... as soon as you launch it your aircraft can turn to a purpendicular flight course because it can control the missile and receive target data via a datalink pod the aircraft carries that will work to about 150km range.

    Fly the missile towards the train line and then turn and fly down the train line looking for the target.. you can fly it high for good visibility or 15m above the track... when it spots the suitable train it can drop down to 2m above the track and hit the engine or the front carriage.

    Another option would be to destroy a bridge in the path of the train... preferably as the train is crossing the bridge... the bridge is a fixed coordinate target and would be easy to hit it would just be a question of timing.

    Of course most of their cruise missiles used terminal guidance so the satellite navigation gets them to the area the target is expected to be and then the terminal guidance... whether radar or optical can locate the actual target and guide the weapon in to hit it precisely.

    Normally you have other aircraft with you that can lase a target for a laser homing missile to hit a moving target, or a TV guided weapon like a Kh-29T or as I mentioned the TV guided Kh-59K with a digital data link and small turbojet sustainer engine can be used.

    Russia will have rather accurate digital maps of the Ukraine and could use radar guided weapons to detect moving targets like vehicles or trains too... the Kh-31 or the Kh-35 would be excellent for hitting train sized targets on the move.

    They have spy satellites that are not in geosynchronous orbits but they don't hover over the region like they do in the movies.

    You need multiple satellites and you likely still wont get 24/7 continuous coverage of every part of the country... but you don't need to continuously track a train to hit it. Or a large group of civilian vehicles that seem to be headed towards the conflict zone instead of away from it with some vehicles towing strange looking trailers with them if you know what I mean...

    Russian Military Satellites: Development and Launches - Page 8 Empty GPS - Russian base stations

    Post  Gazputin Sun May 22, 2022 12:29 pm

    came across this today by chance
    I didn't think you could "turn-off" the satellites
    ( and you can detune them having experienced that myself in the middle of the Pacific 20 years ago or so )

    anyway interesting summary of how they can de-tune it ...
    and the location of Rus GPS groundstations

    Russia will be disconnected from GPS in April-May 2022
    "Roscosmos on April 22 will send technical proposals to the Ministry of Transport and the Federal Air Transport Agency to replace GPS with GLONASS subscriber equipment. It will also be able to receive a signal from the Chinese navigation system," Rogozin wrote on Twitter.

    The consequences of disabling GPS

    in Russia will be noticeable, but not critical.
    To begin with, it is impossible to disconnect a particular country from the GPS purely technically. After all, the orbits of satellites are not stationary, so it is impossible to turn off the satellites responsible for a certain zone:
    each satellite has too large a coverage area.
    However, theoretically, it is possible to disable 11 GPS ground stations located in:

    Kaluga and Sverdlovsk regions;
    Krasnoyarsk Territory;
    Yakutia;
    Irkutsk;
    Magadan;
    Yuzhny Sakhalin;
    Petropavlovsk-Kamchatsky.

    It is they who constantly refine the parameters improving the quality of navigation. This can lead to a decrease in the accuracy of satellite geodesy in Russia and a deterioration in positioning on devices to several hundred meters.

    Russian ground stations in the United States.
    You can't turn off GPS, but you can distort the data.
    In 2008, this was already done

    (this also confirms it is impossible to use GPS to hit a moving target re discussion above )

    Turning off ground stations in Russia is a good thing, they are used to make GPS in those regions more precise by measuring the signals from the satellites from fixed known locations so any error can be measured and used in nearby receivers to correct the location to a better precision.
    In other words a site that is in known position of x y z uses a GPS receiver to find its position via GPS is out by 10m in X an 3m in Y and 4m in Z.... then they can send the information to the US who can adjust the signals to make the signals more accurate for the area... maybe 0.5m, 0.1m and 0.4m off... which will effect the accuracy of the entire region by improving it. But obviously it also improves the precision of the military signal too.

    During the confict in Georgia it was stated that the Civilian signals were turned off in that region... it would not be hard... the satellites have fixed orbits and their civilian signals could be turned off as they approach selected regions and turned back on once they passed those regions, or their accuracy reduced to the point where they were hundreds of kms out making them useless.

    US claims they no longer degrade the accuracy and wouldn't turn it off are not to be trusted... I wouldn't believe them if they said the sky was blue.

    Spacecraft in question (Kosmos-2555 military satellite) burned away in atmosphere after malfunctioning

    https://bmpd.livejournal.com/4527612.html

    Either have more of them in storage for quick replacement or do something about quality control

    The VNIIEM Corporation is working on a satellite project called Geovysota. These are aerodynamically shaped satellites designed to operate in very low orbits and probably look similar to the satellite seen in the attachment. Kosmos-2551 and 2555 may have been the first satellites of this type and it is very well possible that their missions were not failures as widely reported in the media. See the thread on Geovysota:

    AFAIK yes, but it is a global naval system, not a regional tactical ground warfare system.

    The RF Ministry of Defense announced the launch of the Soyuz-2.1v light-class rocket from the Plesetsk cosmodrome

    Pre-launch operations and the launch of the rocket took place in the normal mode, the department noted.

    MOSCOW, 1 August. /TASS/. The Soyuz-2.1v light-class rocket launched on Monday evening from the Plesetsk cosmodrome, it will put into orbit a spacecraft developed for the Russian Defense Ministry, the department of information and mass communications of the military department told reporters on Friday.

    "On Monday, August 1, at 23:25 Moscow time, from the State Test Cosmodrome of the Ministry of Defense of the Russian Federation (Plesetsk Cosmodrome), the combat crew of the Aerospace Forces successfully launched a Soyuz-2.1v light launch vehicle with a spacecraft, developed in the interests of the Russian Ministry of Defense," the statement said.

    It is noted that the pre-launch operations and the launch of the rocket took place in the normal mode. The launch and flight of the rocket was controlled by means of a ground-based automated control complex.

    It is also reported that the ground assets of the Space Forces of the Russian Aerospace Forces took the Soyuz-2.1v rocket for escort. "The Soyuz-2.1v space rocket, which launched at 23:25 (MSK) from the Plesetsk state test cosmodrome, was accepted for escort by ground means of the Main Test Space Center named after G. S. Titov of the Space Forces Air -Space Forces," the statement said.

    The upper stage "Volga" with a military satellite regularly separated from the second stage of the Soyuz-2.1v rocket, which put it into orbit. "The space warhead of the Soyuz-2.1v light-class space rocket as part of the Volga launch unit and the spacecraft launched in the interests of the Russian Ministry of Defense, at the estimated time - 23 hours 34 minutes (Moscow time) - routinely separated from the second stage of the launch vehicle "Soyuz-2.1v", - the message says.

    It calls it an inspector satellite for orbital surveillance, but the name Nivelir seems to mean Spirit Level... as used in surveying and navigation etc...

    Angara-1.2 launch vehicle puts military satellite in orbit

    MOSCOW, October 16. /TASS/. The Kosmos-2560 satellite launched in interests of the Russian Defense Ministry from the Plesetsk Cosmodrome in the Archangelsk Region using the Angara-1.2 light launch vehicle was successfully put into the target orbit, the Ministry told reporters on Sunday.

    The light launch vehicle with the spacecraft blasted off at 22:55 Moscow time on Saturday.

    "The Kosmos-2560 spacecraft launched by combat crews of the Space Force of Russia’s Aerospace Forces from the State Test Cosmodrome Plesetsk was placed on the target orbit at the estimated time and was taken for tracking by terrestrial facilities of the Russian Defense Ministry," the Ministry said.

    Robust telecommunication is being maintained with the satellite and its onboard systems are functioning normally, the Ministry added.

    The description for the first two satellites in that website is probably wrong. The Russian government said the second satellite, which this site says was "dead", was a target for Peresvet and it is likely the first one was a target as well.
